class MultiListbox(Frame): (source)

Constructor: MultiListbox(master, columns, column_weights, cnf, **kw)

A multi-column listbox, where the current selection applies to an entire row. Based on the MultiListbox Tkinter widget recipe from the Python Cookbook (http://code.activestate.com/recipes/52266/)

For the most part, MultiListbox methods delegate to its contained listboxes. For any methods that do not have docstrings, see Tkinter.Listbox for a description of what that method does.

Method	`__init__`	Construct a new multi-column listbox widget.
Method	`__setitem__`	Configure this widget. This is equivalent to `self.configure({key,val`)}. See `configure()`.
Method	`activate`	Undocumented
Method	`bbox`	Return the bounding box for the given table cell, relative to this widget's top-left corner. The bounding box is a tuple of integers `(left, top, width, height)`.
Method	`bind_to_columns`	Add a binding to each `Tkinter.Label` and `Tkinter.Listbox` widget in this mult-column listbox that will call `func` in response to the event sequence.
Method	`bind_to_labels`	Add a binding to each `Tkinter.Label` widget in this mult-column listbox that will call `func` in response to the event sequence.
Method	`bind_to_listboxes`	Add a binding to each `Tkinter.Listbox` widget in this mult-column listbox that will call `func` in response to the event sequence.
Method	`columnconfigure`	Configure all table cells in the given column. Valid keyword arguments are: `background`, `bg`, `foreground`, `fg`, `selectbackground`, `selectforeground`.
Method	`configure`	Configure this widget. Use `label_` to configure all labels; and `listbox_` to configure all listboxes. E.g.:
Method	`curselection`	Undocumented
Method	`delete`	Undocumented
Method	`get`	Return the value(s) of the specified row(s). If `last` is not specified, then return a single row value; otherwise, return a list of row values. Each row value is a tuple of cell values, one for each column in the row.
Method	`hide_column`	Hide the given column. The column's state is still maintained: its values will still be returned by `get()`, and you must supply its values when calling `insert()`. It is safe to call this on a column that is already hidden.
Method	`index`	Undocumented
Method	`insert`	Insert the given row or rows into the table, at the given index. Each row value should be a tuple of cell values, one for each column in the row. Index may be an integer or any of the special strings (such as ...
Method	`itemcget`	Undocumented
Method	`itemconfigure`	Configure the table cell at the given row and column. Valid keyword arguments are: `background`, `bg`, `foreground`, `fg`, `selectbackground`, `selectforeground`.
Method	`nearest`	Undocumented
Method	`rowconfigure`	Configure all table cells in the given row. Valid keyword arguments are: `background`, `bg`, `foreground`, `fg`, `selectbackground`, `selectforeground`.
Method	`scan_dragto`	Undocumented
Method	`scan_mark`	Undocumented
Method	`see`	Undocumented
Method	`select`	Set the selected row. If `index` is specified, then select row `index`. Otherwise, if `delta` is specified, then move the current selection by `delta` (negative numbers for up, positive numbers for down). This will not move the selection past the top or the bottom of the list.
Method	`selection_anchor`	Undocumented
Method	`selection_clear`	Undocumented
Method	`selection_includes`	Undocumented
Method	`selection_set`	Undocumented
Method	`show_column`	Display a column that has been hidden using `hide_column()`. It is safe to call this on a column that is not hidden.
Method	`size`	Undocumented
Method	`yview`	Undocumented
Method	`yview_moveto`	Undocumented
Method	`yview_scroll`	Undocumented
Constant	`FRAME_CONFIG`	Undocumented
Constant	`LABEL_CONFIG`	Undocumented
Constant	`LISTBOX_CONFIG`	Undocumented
Property	`column_labels`	A tuple containing the `Tkinter.Label` widgets used to display the label of each column. If this multi-column listbox was created without labels, then this will be an empty tuple. These widgets will all be augmented with a ...
Property	`column_names`	A tuple containing the names of the columns used by this multi-column listbox.
Property	`listboxes`	A tuple containing the `Tkinter.Listbox` widgets used to display individual columns. These widgets will all be augmented with a `column_index` attribute, which can be used to determine which column they correspond to...
Method	`_pagesize`	No summary
Method	`_resize_column`	Callback used to resize a column of the table. Return `True` if the column is actually getting resized (if the user clicked on the far left or far right 5 pixels of a label); and `False` otherwies.

def __init__(self, master, columns, column_weights=None, cnf={}, **kw): (source) ¶

Construct a new multi-column listbox widget.

Parameters
master	The widget that should contain the new multi-column listbox.
columns	Specifies what columns should be included in the new multi-column listbox. If `columns` is an integer, the it is the number of columns to include. If it is a list, then its length indicates the number of columns to include; and each element of the list will be used as a label for the corresponding column.
column_weights	Undocumented
cnf	Undocumented
cnf, kw	Configuration parameters for this widget. Use `label_` to configure all labels; and `listbox_` to configure all listboxes. E.g.: >>> mlb = MultiListbox(master, 5, label_foreground='red')
**kw	Undocumented

def __setitem__(self, key, val): (source) ¶

Configure this widget. This is equivalent to self.configure({key,val)}. See configure().

Undocumented

def bbox(self, row, col): (source) ¶

Return the bounding box for the given table cell, relative to this widget's top-left corner. The bounding box is a tuple of integers (left, top, width, height).

def bind_to_columns(self, sequence=None, func=None, add=None): (source) ¶

Add a binding to each Tkinter.Label and Tkinter.Listbox widget in this mult-column listbox that will call func in response to the event sequence.

Returns
A list of the identifiers of replaced binding functions (if any), allowing for their deletion (to prevent a memory leak).

def bind_to_labels(self, sequence=None, func=None, add=None): (source) ¶

Add a binding to each Tkinter.Label widget in this mult-column listbox that will call func in response to the event sequence.

Returns

Returns
A list of the identifiers of replaced binding functions (if any), allowing for their deletion (to prevent a memory leak).

def columnconfigure(self, col_index, cnf={}, **kw): (source) ¶

Configure all table cells in the given column. Valid keyword arguments are: background, bg, foreground, fg, selectbackground, selectforeground.

def configure(self, cnf={}, **kw): (source) ¶

Configure this widget. Use label_* to configure all labels; and listbox_* to configure all listboxes. E.g.:
